CO2 Dissociation Curve of Lung Tissue

Abstract
The CO2 dissociation curve of an exsanguinated dog lung was found to be similar to that reported for other tissues. The slope of this curve at normal alveolar CO2 tensions is great enough to have a just-measurable effect on the composition of the alveolar air during normal breathing, breath-holding and other respiratory procedures. It serves to diminish the variations in alveolar PCO2 which would otherwise occur.
